Before:
  call ale#assert#SetUpLinterTest('go', 'govet')

After:
  call ale#assert#TearDownLinterTest()

Execute(The default command should be correct):
  AssertLinter 'go', 'cd ' . ale#Escape(expand('%:p:h')) . ' &&  go vet .'

Execute(Extra options should be supported):
  let g:ale_go_govet_options = '--foo-bar'
  AssertLinter 'go', 'cd ' . ale#Escape(expand('%:p:h')) . ' &&  go vet . --foo-bar'
